WHoohoo, Check Engine turned itself off after O2 replacemnt 850 1997

posted by  someone claiming to be Matthew de Seattle on  Fri May 3 06:55 CST 2002 [RELATED]

Check Engine light on since September. Read codes next day with dealer's help (1997 T5 - can't do it without a reader, one of which I have one on the way) and it was a 212 front O2 sensor. Replaced it a week ago with Volvo replacement O2 sensor, and last nite after 135 miles, I looked down and Pow -- it was not lit. Music to my eyes.

Another Brickboarder mentioned this same thing a few days ago -- the light turning off by itself.

For those who are concerned with O2 sensor part... the Volvo OEM one came with anti-seize already on the threads -- nice touch for someone like me who has limited tools and no garage even. Got it for free so I don't have a price for you.

Removal of old one required 5 minutes of WD40 penetration and open end wrench. Also, the harness was the point of some time and attention, even more than the sensor itself. It's hard to figure out, so if you can see and feel how other harnesses work... do it before trying to replace this sensor because it's very hard to move around/see this harness.

If you don't mind me asking, how much is your scanning tool costing you and how much are O2 sensors?

About $120 U.S., and I think front O2 sensors are around $150 for an OEM.

Where can you buy one of those OBD readers? I have a 97 850 T5, also will it work for my mom's car, she has a 98 V70? Thx,
Nate
